John Poljack, of KeyNumbers makes the calculation:

"According to BP, the world uses 27 PWh of electricity and 90 exajoules to power all cars and trucks, mainly petroleum products. To replace them with electric cars/trucks you would need the electricity generation of China. Replace it all with hydrogen and it's China, USA and Europe combined. Move to synthetic diesel and petrol and it's multiples of global electricity generation.

Those numbers certainly contextualize the problem. Obviously we can hope for efficiency improvements and even optimized systems to minimize growth in energy needs, but they're not going to match the scale of continued growth in transportation and all that energy has to come from somewhere!
